Weedless hook for lures

ABSTRACT

A weedless fishing apparatus includes a hook having a shank, a curved throat portion and a point. The curved throat portion is sufficiently resilient that the point can be moved toward the shank to a retracted or cocked position and so that upon release of the point from the retracted position, the resilient curved throat portion will spring the point back to an extended fish hooking position. A releasable retaining device is provided for retaining the point of the hook in the retracted position for releasing the point of the hook from the retracted position when tension is applied to a fishing line attached to the apparatus.

BACKGROUND OF THE INVENTION

1. Field of The Invention

The present invention relates generally to weedless hooks for use in fishing, and more particularly, but not by way of limitation, to such hooks which are particularly adapted for use with soft bodied lures such as plastic worms.

2. Description Of The Prior Art

It has long been recognized that it would be advantageous to have a fish hook which would have its barb covered until such time as a fish takes the hook or lure attached to the hook into its mouth. Such a hook construction has many advantages. First, it is weedless and since the barb is initially covered it will not hang up upon various obstacles encountered in the water. Second, a fish is much more likely to take such a hook into its mouth without alarm if the fish does not immediately feel the metal hook.

One such device designed for use with soft bodied plastic worms is shown in U.S. Pat. No. 3,890,735 to Serrill. This device includes a multiple barb hook which has the barbed portions thereof cammed outwardly as the hook is pulled forward relative to a surrounding housing, all of which is imbedded in the plastic lure.

Also, many designs have been provided for weedless hooks on hard bodied lures. For example, U.S. Pat. No. 151,394 to Huard et al. discloses a lure having a hook which is initially hidden in the body of the lure, but which is biased radially outward by a separate leaf spring member. A releasing mechanism allows the separate leaf spring member to pivot the hook outwardly so as to hook a fish, when the fish strikes the lure.

Other weedless hooks and lures are shown in the following:

SUMMARY OF THE INVENTION

The present invention provides a fishing apparatus including a hook having a shank, a curved throat portion and a point. The curved throat portion is sufficiently resilient that the point can be moved toward the shank to a retracted position and so that upon release of the point from the retracted position, the resilient curved throat portion of the hook will spring the point back to an extended fish catching position. A releasable retaining means is provided for retaining the point in the retracted position and for releasing the point from the retracted position when tension is applied to a fishing line attached to the apparatus.

Numerous objects, features and advantages of the present invention will be readily apparent to those skilled in the art upon a reading of the following disclosure when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Turning now to the drawings, and particularly to FIG. 1, a weedless fish hook assembly is shown and generally designated by the numeral 10.

The apparatus 10 includes a hook 12 having a shank 14, a curved throat portion 16, and a point 18 having a barb 20.

The apparatus 10 includes a shaft assembly 22 which includes a tubular outer shaft 24 having a forward end 26 and a rearward end 28. The tubular outer shaft 24 has a shaft bore 30 extending through the outer shaft 24 from the forward end 26 to the rearward end 28. Bore 30 may also be described as an elongated inner passage 30.

Tubular outer shaft 24 further includes a side wall having a side opening 32 defined therethrough and communicated with the shaft bore 30

The shank 14 of hook 12 is fixedly attached to the tubular outer shaft 24 such as by welding or braising as indicated at 34. The hook 12 extends from the rear end 28 of tubular outer shaft 24 and the throat portion 16 extends laterally from the outer shaft 24 and terminates in the point 18.

The throat portion 16 is flexible and resilient so that throat portion 16 can be resiliently deformed to move the point 18 toward the shank 14 and outer shaft 24 to a retracted position as illustrated in FIGS. 3 and 4 wherein point 18 extends inward through side opening 32. Upon release of the point 18 from the retracted position, the resilient curved flexible throat portion 16 will spring the point 18 back to the extended position of FIGS. 1 and 2.

A releasable retaining means generally designated by the numeral 36 is provided for retaining the point 18 in the retracted position of FIG. 4 and for releasing the point 18 from the retracted position when tension is applied to a fishing line 38 attached to the apparatus 10.

The releasable retaining means 36 can be considered to include portions of the tubular outer shaft 24, and also includes a hook retainer 40 slidably disposed within the bore 30 of tubular outer shaft 24. The hook retainer 40 may be constructed from a smaller diameter hollow cylindrical tube having an open rear end 42 so that the rear end 42 of hook retainer 40 can be received over the point 18 of hook 12 when the hook 12 and hook retainer 40 are in a cocked position as illustrated in FIG. 4 to hold the point 18 of hook 12 in the side opening 32.

The inner bore 44 of inner tube 40 adjacent rear end 42 may be described as a retaining surface 44 which can be received over the point 18 of hook 12.

As is illustrated in FIGS. 1-4, the hook retainer 40 is slidable within the shaft bore 30 of tubular outer shaft 24. A coil compression spring 46, which may be generally referred to as a resilient biasing means 46, is disposed in the shaft bore 30 forward of hook retainer 40 for biasing the hook retainer 40 rearwardly within the shaft bore 30 toward its cocked position.

A line attachment means 48 which may be made of steel wire is attached to the forward end 50 of hook retainer 40 and extends out of the forward end 26 of outer shaft 24 and terminates in eyelet 52. The fishing line 38 is attached to eyelet 52.

A retaining collar 54 is threadedly connected to shaft bore 30 at thread 56 and abuts a forward end of the coil compression spring 46. Collar 54 has a central opening 58 therethrough through which the line attachment means 48 extends.

Thus, the coil compression spring 46 is contained between the retaining collar 54 at its forward end and the hook retainer 40 at its rearward end. When tension is placed on fishing line 38, and a fish or anything else restricts movement of the apparatus 10, the hook retainer 40 will slide forward within the bore 30 of tubular outer shaft 24 thus compressing spring 46. When tension is released, the spring 46 will move the hook retainer 40 rearwardly relative to tubular outer shaft 24.

FIG. 1 shows the apparatus 10 with the hook 12 in its extended position, and with the coil compression spring 46 extended so as to push the inner member or hook retainer 40 rearwardly so that it closes the side opening 32. When it is desired to use the apparatus 10, the tubular outer housing 24 is held fixed, and the line attachment means 48 is pulled forwardly to pull the hook retainer 40 forward to a position like that shown in FIG. 2 wherein the side opening 32 is no longer blocked. The hook 12 is then bent inwardly until its point 18 extends inward through the opening 32 as shown in FIG. 3, all the while holding the hook retainer 40 forward of the side opening 32. Then while holding the hook 12 bent inwardly, the hook retainer 40 is allowed to slide rearwardly so that the open rear end 42 thereof covers the point 18 to hold the point 18 in the position of FIG. 4 which can be described as a cocked position or a retracted position or a weedless position.

The hook retainer 40 can be described as being in a first position in FIG. 4 corresponding to the cocked position of the hook 12. Subsequently, if a fish grabs the apparatus 10, the fisherman will quickly apply tension to fishing line 38 thus quickly moving hook retainer 40 relative to tubular outer housing 24 to a second position like that of FIG. 3 which allows the flexible throat portion 16 of hook 12 to spring the point 18 back outwardly to an extended position like that of FIG. 2.

When the hook 12 is bent inwardly as shown in FIG. 3, the point 18 reaches approximately to a longitudinal axis 60 of the shank 14 and/or the shaft assembly 22.

The apparatus 10 as shown in FIGS. 1-4 is enlarged to be greater than actual size for ease of illustrating the internal components. It will be appreciated that the apparatus 10 is particularly adaptable for use with elongated soft body lures such as a plastic worm 62 seen in FIG. 5. The worm 62 as shown in FIG. 5 is itself a part of the prior art. The worm 62 has a head portion 64 with a diameter of approximately 3/8 inch. The tubular outer shaft 24 of apparatus 10 when designed for use with a soft bodied lure such as worm 64 preferably has an outside diameter of no greater than about 1/8 inch.

FIGS. 5-9 are a sequential series of illustrations showing a preferred manner of assembling the apparatus 10 with the plastic worm 64.

FIG. 6 illustrates the use of a coring tube 66 to provide a passage 68 for the shaft assembly 22 of the hook apparatus 10. The coring tube 66 preferably is simply a length of hollow tubing of the same diameter as the outer tubular shaft 24 of apparatus 10 e.g., 1/8-inch diameter. The coring tube 66 has a forward end 70 and a rearward end 72. Preferably the passage 68 is formed by piercing the side of the worm 62 as indicated at 73 and then pushing the coring tube 66 forward substantially coaxially with the head portion 64 of worm 62 until the forward end 70 extends out a forward end 74 of worm 62. The thin walled coring tube 66 actually cuts a cylindrical core of plastic from the worm 62 and when the coring tube 66 is removed as illustrated in FIG. 7, a passage 68 remains in the worm 62.

After the core passage 68 has been formed, the apparatus 10 can be easily assembled with the worm 62 in the following manner. The shaft assembly 22 which can be described as having a forward end defined by collar 54 with the wire 48 and eyelet 52 extending therefrom first has that forward end inserted through the tear 73 and then threaded forward through the passage 68 until the line attachment means 48 and eyelet 52 protrude from the forward end 74 of the worm 62 as illustrated in FIG. 8.

Then, the plastic worm 62 is held firmly about the head portion 64 so as to hold the tubular outer shaft 24 in place while pulling forward on the wire 48 to move the hook retainer 40 to a position like that of FIG. 2. While holding the hook retainer 40 forward the hook 12 is bent inwardly to pierce through the soft plastic worm 62 and to extend through the side opening 32 of tubular outer shaft 24. While holding the hook bent inwardly, the wire 48 is released allowing hook retainer 40 to be biased rearwardly to a position like that of FIG. 4 wherein the hook 12 is held in a cocked position with the point 18 hidden within the plastic worm body 62 as illustrated in FIG. 9.

The plastic worm illustrated in FIG. 9 is ready for use in fishing. A fishing line 38 will be attached to the eyelet 52. When a fish takes the lure 62 into its mouth, tension applied to the fishing line 38 will cause the hook 12 to be released and to spring outwardly into a fish hooking extended position.

Alternatively, the apparatus 10 can be assembled with a cored worm like that of FIG. 7 by first unthreading collar 54 from outer tube 24 and pulling inner tube 40, wire 78, spring 46 and collar 54 out of the outer tube 24. Then the outer tube 24 can be inserted through tear 73 and threaded forward until it extends from the forward end 74 of worm head 64. Then the inner tube 40, wire 78, spring 46 and collar 54 can be re-inserted into outer tube 24 and the threaded connection 56 can be remade to result in the assembly shown in FIG. 8.

As a further alternative, the coring of the worm as shown in FIGS. 6 and 7 can be eliminated. The apparatus 10 can simply have its forward end forced into the worm to form tear 73 and the shaft assembly 22 can then be forcibly threaded forward through the soft worm body to the position of FIG. 8.

The Alternative Embodiment Of FIG. 10

Various forms of the apparatus 10 may be provided for use with different commonly used types of lures. For example in FIG. 10, a shortened apparatus 10A is provided for use with relatively short soft bodied lures such as plastic grubs. A plastic grub is shown in phantom lines and designated by the numeral 76. All internal working parts of the apparatus 10A are the same as those of the apparatus 10 except for their longitudinal dimensions.

The Alternative Embodiment Of FIG. 11

Another embodiment of the apparatus is shown in FIG. 11 and designated by the numeral 10B. The apparatus of FIG. 11 is similar to that of FIGS. 1-4 except that the hook 12B has been modified so that its flexible throat portion 16B includes a safety pin type bend 78 to aid the resiliency of throat portion 16B.

The Alternative Embodiment Of FIG. 12

FIG. 12 illustrates another alternative embodiment of the apparatus 10 which is designated as 10C. The apparatus 10C is located within a rigid lure body 80 which has a side opening 82 in registry with the side opening 32 so that the point 18 of the hook 12 can extend through the side opening 82 in lure body 80 and through the opening 32 to be held in a cocked position.

Thus it is seen that the apparatus and methods of the present invention readily achieve the ends and advantages mentioned as well as those inherent therein.
